Book excerpt: Why do ordinary people turn to psychology in the hopes of making themselves healthier, wealthier, and happier? Governed by Affect offers a multi-sited history of psychology and its role in American public life. Focusing on a series of transformations since the 1970s, the book examines the rise of psychology as a health science and the discipline's growing entanglements with public policy inspired new theories of inattentive and unconscious affect, which have come to structure health care, education, the economy, and how we understand ourselves.
